Database excecution in local developement / WP 5.4

Hi,
I’ve came across some issue with database connection.
While I try to update or create some posts/pages in local wordpress instance, the interface throws me to the general post list and in best case scenario, saves my last post to draft, but without any content.
I’ve been trying to debug this in my own environment (I work on Manjaro Linux / MariaDB 10.1) because I’ve seen that I can’t execute any query, even as a root user. After reinstallation the problem with manual queries gone, nevertheless I still can’t create any post.
To compare I’ve tried the same on WP 5.3, and there was no problem.
Is there any solution to that issue? Han anyone else encountered that?
